When brought to the proletariat from the capitalist class, science is invariably adapted to suit capitalist interests. What the proletariat needs is a scientific understanding of its own position in society. That kind of science a worker cannot obtain in the officially and socially approved manner. The proletarian himself must develop his own theory. For this reason he must be completely self-taught.

The obvious objection that the individual is very little concerned whether he himself is diligent and enthusiastic, and that it is of greater moment to him that everybody else should be, is either completely ignored or is insufficiently dealt with by them. They believe they can construct a socialist commonwealth on the basis of the Categorical Imperative alone. How lightly it is their wont to proceed in this way is best shown by Kautsky when he says, "If socialism is a social necessity, then it would be human nature and not socialism which would have to readjust itself, if ever the two clashed." This is nothing but sheer Utopianism.
